This is about USB instrument control - not USB-based instrumentation, such as Pico, Signal Hound, etc.
This is just a high-level question - nothing specific.
I've been considering taking some time and fiddling with instrument control via USB. Most of my equipment has either a GPIB, RS232 or USB connection. I'm not even looking at the GPIB as the Fluke meter also has an RS232 port and came with USB/UART cable. But I'm getting specific and that's not my intent.
My primary question is do you guys use USB hubs when/if you do control? I'm planning to use a laptop to tinker with this (i7/12GB RAM, W7pro) and of course, it has a limited number of USB ports.
Do you use isolated USB hubs? I have a BlackBox branded isolated hub I inherited some time back. It seems that all isolated hubs are bandwidth limited to 12Mbs/sec. This doesn't seem to be a huge limitation as far as a reference to RS232 control. I like this hub and have used in other situations since I've had it. It allows for an external power supply via a terminal block. That's come in handy with a couple ham radio projects in the past when using a linear supply for the hub.
So, any general dos/don'ts? Your experience has confirmed what? Whatever I do, don't do .......
Thanks in advance for any words of wisdom you may have.
